SPECIFICATION forming part of Letters Patent No. 402,872, dated May 7, 1889.

Application filed October 22, 1888.

To all whom, it may concern.-

Be it known that I, LE ROY C. TRYON,a citizen Of the United States of America, residing at Marseilles, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Grain- Veighing Machines, of which the following' Is a specification, reference being had therein to the accompanying drawings, and the letters Io of reference thereon, forming a part of this specification, in which- Figure l is a perspective view of the grainweigher as it would appear ready for use and connected with the discharge-elevator of a I 5 separator. Fig. 2 is a perspective view of the oscillating chute for alternately conducting grain to the buckets, of the mechanism for oscillating said chute, and of the lower end of the grain-spout leading from the elevator zo of a grain-separator to the buckets connected with the chute. Fig. 3 is a central vertical section of the lower end of the grain-spout and Oscillating chute, the broken lines showing the reverse position of the chute. Fig. 4 is a detail perspective view of the oscillating chute and oscillating aprons operating with said chute for catching and conducting any grain that might be scattered and wasted by the chute by reason of its Oscillation.

3o Referring to the drawings, T T are a pair of similar and equal oscillating graiirbuckets, triangular in form in cross-section, and connected with each other so their mouths are at right angles with each other, and secured to rock-shaft S, passing between them, by means of the radial arms lV NV and XV VW, the said shaft being boxed at each end in the rectangular frame B,which is suspended from the lower end of the grainspout L by means 4o of the bail F. The outer ends of arms WV XV are respectively provided with springecatches Z, for respectively and alternately engaging with the inner ends of the scale-beams D D, fulcruined in posts I I,when the buckets are oscillated.

R is a cranked rock-shaft boxed at each end in bail F, and carries in its central cranked portion the oscillating grain-chute K. Said sha-ft is provided at one end with. a crank, c.,

Serial No. 238,877. (No model.)

which is connected with crank-lug n on spider 5o B of arms XV XV ,by Ineans of link c, in such manner that when shaft S,with its buckets T T, oscillates the shaft R will rock in the opposite direction and oscillate chute Kin the opposite direction from said buckets for the pur- 5 5 pose of alternately conducting grain thereto.

T is a tally device secured to frame B, and is connected with crank X on shaft S by Ineans of pitman Y, by means of which tally au accurate accountmay be kept of the amount of 6o grain passing through the buckets. Any kind of a tally device may be used that can be operated by the buckets.

L is a grain-spout leading from the discharge-elevator of a separator to the chute K.

d is a block or rest secured on the top of the spout L, and is provided with a groove, d', for holding the bail F.

The outer end of spout L is closed by means of the stop 71 for the purpose of arresting the 7o grain in its descent, so it will not fall beyond the vbuckets or strike the buckets with force and prevent the scale-beams from weighing accurately. Said stop is intended generally to be made of metal and extend below the 75 lower side of the spout and have integral side iiaps, h', for securing it to the outer sides of the spout, as shown. The said stop has its lower side inclined backward, so as to cause the grain after being arrested to -be thrown 8o backward against the chute II, so it will drop of its own gravity to the buckets from the chute, and not stiike ,the buckets with such force as to interfere with the weighing mechanism. The lower floor of the spout L stops short of the end of the spout, so as to leave a discharge-opening between it and said stop.

J .I are a pair of oscillating aprons hinged at their upper side, respectively, to the shafts m m, connected with bail F by means of the 9o cross-arms I I, and heldin proper position by a brace, b. These aprons are connected at their lower part by means of the link F', and are provided with sides J, for preventing escape of grain that may fall On them. 9 5

The aprons .I .I are arranged. one on either side of the chute K and connected with said chute through the medium of pitman p and crank O3, secured on shaft R of said chute in such manner that said chute and aprons oscillate simultaneously in the same direction, so that when the chute K is oscillated quickly and throws grain upward and outward by such oscillation such grain will fall on the aprons alternately and be conducted to the buckets and not lost, and such grain will be conducted 4to the' bucket to be filled instead of the one set for the desired number of pounds by the v proper adjustment of the weight G thereon, it will oscillate downward and discharge its contents in some receptacle-such as a wagonboX-and such oscillation will place the opposite bucket in proper position connected with the opposite scale-beam, and also simultaneously oscillate the chute K in the opposite direction, causing the grain to fill said opposite bucket and discharge its contents in like manner as the other, and so on alternately the buckets will be filled and discharge their con tents, and through their connection with the tally will record the amount of grain passing through them.

In this invention the principal new features are the oscillating aprons J J, arranged, as shown, to operate in connection with the oscillating chute K and the grain-bucket-s, and also in the grooved rest d, arranged on the spout L and adapted to support the grainweighing mechanism by means of the bail F resting in its groove. I therefore do not'in this instance claim, broadly, the other parts of this device when disconnected from the parts I deem to be new and now claim, and for the reason that I have already made claims for such parts in former applications.

Having thus described my invention, whatl I claim as new, and desire to secure by Letters Patent, is as follows, to wit:

1. In the grain-weighing machine shown and described, the combination of the oscillating chute K and connected aprons J J, arranged to oscillate in the same direction as said chute, substantially as and for the purpose set forth.

2. In the grain-weighing machine shown and described, the combination of the oscillatingbuckets T T, oscillating chute K, and oscillating aprons J J, substantially as and for the purpose set forth.

3. In the grain-Weighing machine shown and described, in combination with the oscillating chute K, the oscillating aprons J J, and the mechanism, substantially as shown, for operating said aprons, as and for the purpose set forth.

4. In the grain-weighing machine shown and described, the grooved rest d, in combination with the bail F and the grain-weighing mechanism, and the spout L, having the stop h, for closing its outer end, substantially as and for the purpose set forth.
